To all whom it may concern: Be it known that I, CLARENCE O.-LEDERER,

a citizen of the United States, residing at Foster,

useful Improvements in Hand-Lever Mechanism for Cultivators; andI do declare the following to be a full, clear, and exactldescription of the invention, such as will enable othersskilled in the art to which itappertains to make and use the same.

This invention relates to hand lever mechanism for cultivators. t, I One object of the invention is to provide a device of this character which may be quickly and easilyand removably attached to a plow or cultivator beam of ordinary construction, making little or no change in the beam to which it is to be attached. Another object is to provide forv automatic vertical adjustment of the fender plate, so as to prevent injury thereto in case it collides with a rock, stump, root or other obstacle.

Another object of the invention is to provide a deviceof this character whereby the plowman or operator may quickly and easily adjust the fender vertically, according to the depth of the plowing, and may raise the fender plate a distance ground when desirable,

Another object is to provide a device of this character which consists of few and.

simple parts which may be cheaply manufactured and assembled so thatthe cost of manufacture is reduced to a minimum.

Other objects and advantages may be come apparent to persons who read the following details of description'in connection with the accompanying drawings, in which:

Theplow beams 14 and151are also of ordinary construction, but they are combined with the otherelements of theinvention, as hereinafter set forth'andclaimed, IWhere plow beams ,ofthis ,charactenare secured spond with similar partsthroughout the several v1ews, the frame 10, wheel 1;1, seat I 12, and plow plates 13, being of ordinary together by; a bolt or rivet adjacent their rear ends, such bolt orj rivet maybe removed so'as to replace the same with a bolt or securingelement. 1 6, which not only secures the plow beamstogether, but also formsa means for attaching the other elements of I the invention, as will' presently appear. I The invention consistsbroadly of the bolt 5 16, a disk or segmental member 17, a second disk or'plate 18, an arm 19, afender v plate 20, a hand-lever 21, and a spring 22. I a V The segmental member or casting17 is formedwith a groove 23, a series of teeth 24, a hub25, and, a bore or: aperture 26,

which is concentric withthe hub 25. The I bolt on securingelement '16 extends through-l the aperture 26 and through the beams and 15', and secures the beam 15 in the recess 23,, at-thesame time securing the plate 18 on the end of thehub 25. Thebolt' 16 is preferably provided. with two I nuts which, cooperatelto prevent disengagementof the,

bolt 16, from the aperture 26. I The plat e18 is preferably formed from a blankof sheet metal and is provided with an annular flange. 27, which is notched to provide shoulders 28 and 29. The shoulders Y 28; are spaced f apart approximately equal the distance across the hand-lever 21 where the latter extends between theseshoulders;

and this pain of shoulders, as well as the shoulders. 29' extend laterally of the body of the plate 18 toward the body of the member .2

17. The length'offthe'shoulders 28, how-- ever, is several times greater than the thicke s Q' as ha -le 15mm w re provided with a bearing aperture 80 (see Fig. 8), which is longer than the diameter of the hub 25, sothat this lever may be By referring to Fig. 7, it will be seen that swung laterally of its length into-the position shown in Fig. 6, so as to release the lever 21 from one of thenotches 24:, and engage it with another of these notches without disengaging the lever from the:

space between the shoulders 28. In other words, the hand-lever 21 is contmually in engagement with the 1 notch between the shoulders 28 and adapted to be in andout of engagement with the notches 24. It will be seen, therefore, that when the lever 2l is swung on its pivot element (the hub 25),-

this movement of the'lever turns the plate 18 on its pivot element (the bolt 16) thereby shifting the position of the shoulders '29.

The arm 19 is adapted to rest uponone'of the lower shoulders 29, while the corresponding one of the upper shoulders may be employed for pressing the arm 19 downward.

an obstruction therebyavoiding breakage or distortion of the fender plate and arm. Re-

ferring again to Fig. 7 it will be seen that an arm 31 is formed integrally with the arm 19 and extends in a diametrically-opposite direction" thereto and cooperates with the other pair of shoulders 29, and withthehub 25 for supporting the fender plate in each of its adjusted positions.

The compresslon spring 22 is disposed between the plate 18 and :the arm 19, and

presses the latter against the lever 21, so as to cooperate with, the arm 19 forholdlng the lever 21 in whichever of the notches 24.-

it is placed.

Referring now to Fig. 1, it will be seen that the handle 21 is convenientlylocated with relation to the seat 12, so that the arm 19 and fender 20 may be adjusted by a driver or operator sitting in the :seat .12. Obviously, this results in a great saving of time, as. no tool is required for adjusting the fender plate, and the time which would'be required for obtaining and applying a tool is eliminated; and moreover, the time of: dismounting and remounting the machine is.

eliminated, for when the driver wishes to raise or lower thefender plate, he merely presses the lever '21 laterally, and then pushes or pulls the same. forward or rearward until the desired position of the fender plate20 is .attained,'and then allows the spring 22 to press it into the adjacent notch 24:. This is of very great importance when theplow or cultivator is to be turned at the end of a row, for it is then desirable to raise the fender plate out of engagement with the ground, and above the tops of the plants being cultivated. This may be donewithout, raising the shovels or plates 13, or,'if desirable, the beams 14 and arm 19 may be raised bodily in the usual manner.

Although I have described this embodiment of my invention very specifically, it is not intended to limit this invention to these exact details of construction and combination of parts, but I am entitled to make changes within the inventive idea set forth in the foregoing description and following claims. a

What I claim is: I V

The combination with a beam; of a segmental member formed with a groove in which said beam is seated, said member also being formed with an axially apertured hub and with a series of teeth; an arm pivotally mounted on said hub and being adjustable for a useful purpose; an actuating lever pivotally mounted on said hub; a plate having shoulders extending toward said segmental member; and a securing element on which said plate is pivotally mounted, said securing element extending through said beam and apertured hub and plate and securing all these elements together.

5. In combination, a pivotally mounted element to be adjusted, a segmental member Copies of this patent may be obtained for mounted element being engaged with and movable by said connecting member, said actuating lever being movable into'alternate engagement with said notches while continua'lly extending between said shoulders and being coiiperative with the latter for imparting said rotary movement to said connecting member.

In testimony whereof I have hereunto set CLARE-NOE o. LEDERER.
